Sister of man accused of murdering Louisiana mother and child says she reported his past crimes

The sister of a man accused of killing a Louisiana mother and her 3-year-old child says she has been warning Mississippi authorities about her brother's questionable behavior for years. Dixie Hemphill reacts to the arrest of her brother, Daniel Callihan, in Jackson on Thursday. Callihan is accused of killing Callie Brunnett in Louisiana and kidnapping her two children. Authorities say he took them to Bozier Drive in Jackson, where he killed Brunett's 3-year-old daughter. Upon leaving Jackson police headquarters, Callahan admitted to the crimes he is accused of. “I have no reason for what I did. All I'm saying is I was sober and only taking Lexapro and I was diagnosed with a personality disorder multiple limit,” Callahan said. Hemphill says his brother has been troubled his whole life and is the mastermind of the crime. She says his actions against Brunett's family were horrific. She says her brother dated Brunett 13 years ago. “I've met his kids twice…I feel so bad for the parents, just to know why,” Hemphill said. Hemphill says she went to the Mississippi Bureau of Investigation and the Lincoln Sheriff's Department about her brother's behavior more than a year ago. She said Callihan once admitted to her that he had molested a minor and also participated in the death of a missing person. man. She said they didn't take her seriously. “I just wanted someone to take us seriously because look what happened and the Lincoln County sheriff said there was no merit in him killing anyone, but then he diagnosed him with schizophrenia and let him out of those doors,” Hemphill said. She said Callihan aimed to live a life like her father. “He was classified as a serial killer and we even tried to tell MBI that he wanted to be a prodigy of his father and that he was writing his own book, except that he was going to succeed his father and he did,” Hemphill said. The Lincoln County sheriff said he did not ignore Hemphill's warnings. “An allegation was made against him in a sexual battery case. This case was investigated and presented to a grand jury…The grand jury did not indict him on any of these charges,” Sheriff Steve Rushing said. He said there simply wasn't enough evidence to charge Callihan on those allegations. We contacted the Mississippi Bureau of Investigation and received no comment.
